## (contributed doc: integrating gitolite with monkeysphere)

This document attempts to describe one way to integrate
[Monkeysphere](http://web.monkeysphere.info/) authentication
with [gitolite](http://github.com/sitaramc/gitolite).

We presuppose that you have a system with a new enough
version of Monkeysphere to support ssh `authorized_keys`
options, and that you are not making use of
monkeysphere-authentication on this system.

As a first step, import the key or keys you wish to
act as Monkeysphere certifiers into the GnuPG public
keyring of the gitolite user (for example,
`gpg --keyserver pool.sks-keyservers.net --recv-keys B0AE9A02`)
Then edit such keys (`gpg --edit B0AE9A02`) and assign them
*ultimate* ownertrust.

Next install a script of this nature as `post-update.secondary`
in the `hooks/` directory of the `gitolite-admin` repository.  You can also
follow the "using hooks" section in gitolite's "admin" document to let
gitolite put your new hook in the correct place.

	#!/bin/zsh
	
	# this should use locking
	
	pushd ${GL_ADMINDIR}
	
	if [[ -d monkeydir ]]
	then
	    cp ~/.monkeysphere/authorized_user_ids ~/.monkeysphere/old-authorized_user_ids
	    rm -f ~/.monkeysphere/new-authorized_user_ids
	    for i in monkeydir/*.pub
	    do
	        username=$i:t:r
		for j in ${(f)"$(<$i)"}
	        do
	            cat >> ~/.monkeysphere/new-authorized_user_ids <<EOF
	$j
	  command="/usr/share/gitolite/gl-auth-command $username"
	  no-port-forwarding
	  no-X11-forwarding
	  no-agent-forwarding
	  no-pty
	EOF
	
	        done
	    done
	
	    mv ~/.monkeysphere/new-authorized_user_ids ~/.monkeysphere/authorized_user_ids
	    monkeysphere update-authorized_keys
	fi
	
	popd
	
	ADMIN_POST_UPDATE_CHAINS_TO=hooks/post-update.tertiary
	
	if [[ -x $ADMIN_POST_UPDATE_CHAINS_TO ]]; then
	    exec $ADMIN_POST_UPDATE_CHAINS_TO "$@"
	fi

Finally, place *username*.pub files containing OpenPGP IDs into
 a directory called `monkeydir/` in the root of the gitolite-admin
repository.  If everything has been set up correctly, adding
and pushing these files should then result in the appropriate
generation of `~/.ssh/authorized_keys`.
